Slow Surface Runoff
Reduce the speed and concentration of water moving across paving and landscaped areas.
Site Water Management • Toronto & GTA
Landscape Drainage & LID Solutions in Toronto & the GTA
SYG Landscape plans and builds integrated landscape drainage systems for residential properties across Toronto and the GTA, coordinating grading, runoff, permeable paving, planting and safe overflow with the complete outdoor project.
The problem
Signs Your Property Needs Better Landscape Drainage
Standing water, washed-out soil, settling pavers and runoff moving toward structures can indicate that the site is not managing rainfall effectively. The right response begins by understanding elevations, soil conditions, downspouts, hardscape transitions and where water can move safely.
A drainage solution should not simply move water to another part of the property. We review how water enters the site, where it travels and where infiltration, temporary storage or controlled overflow may be appropriate.
A better approach
How Low Impact Development Manages Rainfall
Low Impact Development manages rainfall close to where it lands through infiltration, filtration, temporary storage and planned overflow. The correct approach depends on the property rather than one standard product.
Support Infiltration
Return rainfall to suitable soils where site conditions and required setbacks allow.
Reduce Erosion
Control concentrated flows that can wash out soil, mulch, planting beds and aggregate.
Plan Safe Overflow
Provide a controlled route for water when rainfall exceeds the normal capacity of the system.

Integrated planning
Landscape Drainage Planned With the Whole Site
A drainage solution should not simply move water to another part of the property. We review how water enters the site, where it travels and where infiltration, temporary storage or controlled overflow may be appropriate.
The drainage strategy is coordinated with patios, walkways and retaining walls, planting areas and other planned landscape work so grades and transitions support the complete outdoor space.
Core solutions
Landscape Drainage & LID Solutions
Every property behaves differently. The appropriate system is selected according to elevations, soil conditions, existing structures, proposed hardscaping, utilities and applicable municipal requirements.
Grading & Surface Drainage
We review elevations, slopes, downspout discharge and hardscape transitions to direct water away from vulnerable areas and toward an appropriate drainage route.
Permeable Paving Systems
Open-joint pavers and carefully constructed aggregate layers can allow rainfall to move through the surface where site conditions permit.
Rain Gardens & Bioswales
Depressed planting areas and vegetated swales can slow, filter and temporarily hold runoff from roofs, lawns and paved areas.
Soakaway Pits & Infiltration Trenches
Below-grade stone reservoirs or infiltration trenches can provide temporary storage where soils, utilities, setbacks and overflow conditions allow.
Our process
Our Landscape Drainage Process
From the first site review to final flow checks, we coordinate drainage, grading and landscape construction so each stage supports the complete outdoor project.
- 01
Step 1: Site Consultation
We review visible drainage patterns, pooling, erosion, downspouts, elevations and the proposed use of the landscape.
- 02
Step 2: Drainage & Grading Strategy
We coordinate infiltration, collection, grading and overflow with the proposed patios, walkways, planting and other site improvements.
- 03
Step 3: Integrated Construction
Construction includes the specified slopes, base layers, drainage components and landscape transitions required by the approved plan.
- 04
Step 4: Final Flow Review
Finished grades, transitions and visible flow paths are reviewed before the drainage and landscape work is completed.
